Thanks everyone. I sent an email to the Contact Us link. It's possible DJ Sures...our lab students are quite careful. No biggie...if you think it is a servo, can we just buy one from you?

Best, Chad

BTW: This system has been extremely useful in our lab. Thanks.

That's really good to hear I'm certain who ever is handling your issue will resolve it quickly These little servos will last a long time if taken care of, we have only burned one or two in the last year. If your students are using them, it may be a small learning lesson and occasionally might be damaged. If you end up going through a few, you can get a few spares here: Micro HDD Servo

DJ What are the hard limits of the vertical head servo? Is it really 1-180? I kept mine to 160 and it still died.

More importantly, I am trying to have jd walk with his head looking downwards, but after every motion (forward, right, left) his head resets to the 90 mark. Having to reset his head after each movement probably contributed to the burn out. I looked at the action and the walk frames and I do not see a servo command to reset the head (the head is at -1 in the frame). Where is it resetting? and can I remove it or make a custom walk command?

Modify all frames to -1 that you use. Including all frames in Stop, forward, left, right, etc..

If the head servo moves, an action that uses a frame is obviously being used somewhere.

The servo head limits are specified in the Init script for the JD project.

Thanks, I thought I caught them all, but I'll look again

I have had to replace Forward, Left and Right with my own versions. My only question is that even though I set the frame speed to 0 (max) my forward command runs about half as fast as the built in. Mine is a copy without resetting servo D0 or D1, but is otherwise identical. Is there any way to speed mine up or is it just the difference between a built in and custom command?

When you assemble the frames into actions, you have values for Delay and Steps. Blue question marks explain more. You can also view the manual page for the Auto Position to see how it works and follow along with tutorial videos. We have spent a significant amount of time (thousands of hours) creating tutorials and videos - and these questions i'm answering are in there
